Recap: Upgrade Shop

Part of the Building Real Games section of Coddy's Unity journey. Lesson 11 of 60.

This chapter wired buttons to code, kept the screen in step with the numbers, and turned buttons on and off. The shop puts them together.

Challenge

Easy

Build the mine's shop.

In Start(), hook the buttons: Mine adds perClick to coins; the pick (pickCost) adds 1 to perClick and costs 10 more; the lantern (lanternCost) adds 3.
Write Refresh(), called in Start() and after each click: Coins: 12, Pick: 20, Lantern: 25 or Lantern: owned. Only affordable, unowned upgrades are interactable.

Press Play and buy both upgrades. Then Check.
